Oxygen Interference Configuration
This option is available to take into account the
influence of some components or gases in the
sample during the measurements. By default all
available interference corrections are disabled.
• Select CO
2
, H
2
S or all disabled
• Select Chlorinity, Salt or disabled. For
chlorinity or salt, it is required to enter the
actual concentration in sample.
Measured Data Storage
There is one measurement file which contains the
data generated by the measurement cycle.
The current measurement file is updated in
volatile memory, and regularly copied in non-
volatile memory (file back-up). At start up, the
measurement file in volatile memory is updated
with the file from the non volatile memory.
The measurement file can be managed as a
r o l l i n g b u f f e r . T h e m a x i m u m n u m b e r o f
m e a s u r e m e n t s i s r e a c h e d , t h e o l d e s t
measurement is discarded, except in “store once”
mode where no storage is made once the buffer is
full.
Adjust the parameters for recording and storing
measured data.
Storage mode selection:
• No storage
• Store once: When volatile memory is full
(1,000 positions), measurement
recording stops
• Rolling buffer: When volatile memory is
full, the latest measurement set replaces
the oldest (first-in, first-out basis)
• RAM (volatile memory) time: Delay in
seconds between two recordings of
measured data.
• FLASH (non-volatile memory) time:
Delay in seconds between two data file
transfers from volatile memory into non-
volatile memory. Last data file erases
previous one.
Buttons:
• Open data: Opens a table containing the
measured value stored in the volatile
memory
• Purge data: Clear all data in the volatile
and non-volatile memories
• Start logging measurement: In store once
mode, starts and stops the measurement
recording session. Measurement
recording is stopped when buffer is full
When any of the following parameters are
modified, the measurement stored in the
measurement file becomes inconsistent, and the
measurement file is erased:
• The date or time
• The gas unit
• The temperature unit
• The pressure unit
